Eagle Plains Acquires 100% Interest
in Yukon Silver/Base-Metal Deposit
Cranbrook, B.C.: Eagle
Plains Resources Ltd. (EPL:CDNX) announces that staking activities
have been completed on the Blende silver/base-metal
deposit located in the Wernecke Mountains, approximately
65 NE of Keno in central Yukon Territory. A total of
16 quartz claims covering approximately 800 acres were
located over the deposit and adjacent areas with high
exploration potential.
The Blende is a carbonate-hosted deposit on the south
edge of the Mackenzie Platform, hosted by Middle Proterozoic
Gillespie Group dolomite. Based on exploration work
to the end of 1991, drill-indicated reserves are reported
as 19.4 million tonnes grading 55.9 g/t silver and
5.85 % lead-zinc, located in the two zones. On surface,
the
deposit is outlined by an open-ended 4.8km-long soil
anomaly which contains values up to 10 000 ppm Zn.
Most geophysical methods including IP, VLF and Max-Min
EM
work exceptionally well due to the inert nature of
the host dolomite. Diamond-drilling carried out in 1991
by Billiton Metals Canada Ltd. delineated two separate
zones (East Zone and West Zone), and established that
the deposit is non-acid generating and could be mined
by open pit methods, with a stripping ratio of 2.1:1.
The deposit consists of a near-surface steeply dipping
tabular body which is conveniently located on a ridge
crest. Preliminary metallurgical studies indicated
no
significant concentrations of deleterious elements.
Although initially explored as an open-pit target,
Eagle Plains management feels that there is good potential
to develop the property as an underground operation.
Numerous high-grade intersections have been reported
by past operators, including hole 88-02 which assayed
282 g/t (8.22 oz/t) silver, 12.2% lead, and 4.4% zinc
over 19.8m from a depth of 70.7 to 90.5m. Hole 88-03
returned 8.5m grading 550.1 g/t (16.04 oz/t) silver,
15.3% lead and 4.6 % zinc from 118.0 to 126.5m, and
hole 90-15 intersected 9.5m grading 351.2 g/t (10.24
oz/t) silver, 14.11% lead, and 6.59% zinc from 60.1
to 69.6m. Step-out drilling in 1994 confirmed the
continuation
of ore-grade mineralization westward, with the addition
of significant copper values. Hole 94-81 contained
14.9 m of mineralization which assayed 228.4 g/t (6.66
oz/t)
silver, 9.71% lead, 5.48% zinc, and 0.78% copper from
9.2m to 24.1m, while hole 94-84 intersected 8.5m which
returned 136.1g/t (3.97 oz/t) silver, 6.74% lead,
3.65% zinc, and 2.43% copper from 45.5-54.0m.
Mineralization at the Blende was originally noted
by the GSC in 1961 and was first staked in 1975 by Cyprus
Anvil Mining Corp., which carried out mapping and
geochemical
sampling later in the year. Archer Cathro & Associates
(1981) Ltd. restaked the property in April 1981 and
conducted trenching and rock sampling from 1981 to 1984.
NDU Resources Ltd. purchased the property in 1987, and
in 1988 drilled 3 holes (718 m) and explored by mapping
and hand trenching. In 1989 NDU carried out mapping,
road construction, soil sampling, magnetic and VLF-EM
surveys. Billiton optioned the property in 1989 and
as project operator drilled 15 holes (3659.7 m) in 1990.
Billiton’s 1991 work included completion of the
soil geochemical and geophysical coverage, drill-testing
of the deposit over a 3.3 km strike length, and preliminary
metallurgical tests. The 1991 drilling consisted of
62 holes totaling 11,525m, including 15 holes in the
West Zone, 34 holes in the East Zone and 13 holes in
the central area between the two zones. Billiton elected
in 1993 to covert its interest to a 10% net profits
royalty. In 1994 NDU drilled 7 step-out holes (596m)
which successfully extended the West Zone 150m further
westward (the West Zone remains open in this direction).
This activity is the last recorded exploration of the
property. In March, 1998 NDU merged with United Keno
Hill Mines Ltd. (UKHM) and the property came under the
control of UKHM, which subsequently went into receivership.
Eagle Plains consultants in Whitehorse commenced staking
immediately after the original claims expired.
Through its employees and consultants, Eagle Plains
Resources continues to adhere to its strategy of acquiring
quality mining and exploration projects through research
and staking activity. The company now has a portfolio
of more than 20 gold, silver and base-metal properties
and believes that the challenges facing the mining
industry today offer unprecedented growth opportunities
for aggressive,
well-funded junior exploration companies like Eagle
Plains.
